A method to determine C1–C5 hydrocarbons, together with hydrogen sulphide and carbon dioxide, in reservoir crude oils was developed based on a splitting system using a PVT (pressure, volume, temperature) laboratory separator. The associated gas derived from this operation is analysed by gas chromatography (g.c.) and the gas volumes of the constituents are converted into liquid volumes employing conversion factors, following adjustment of the PVT volumetric data to standard conditions. This method was found simple, efficient and accurate, with no loss of lighter components, as indicated by comparison of results with those of cold distillation.
Our PVT Oil/Gas GC are specially designed with compact and portable features. H2 is also as carrier gas for good separation of compositions.
